Pretty much all the main religions can be summed up as don’t be an asshole to people. If you ignore all the fairytales and bullshit rules that’s the general idea. No religion is correct because all religion is, is taking something beyond human understanding and trying to force it into a little box. As for christianity itself there is many reasons to hate it. Not following what they preach, constant hate and discrimination towards other communities, an extremely bloody history, and it being used to support flawed arguments or control populations.
